It hasn't done that sagging thing since, and my battery has been fine again since. I find about every month or two, I come out to find a totally dead battery. It is intermitent, which is the hardest to find.

I am planning on instaling a 2nd battery in the engine area connected to a switch, but a 1-way charge setup. I want a setup where both batteries get a charge (to keep both at fully capaicty), but a switch that controls which battery is being used for the accessories. That way if the battery gets drained one night, I just pop hood, turn switch and go (and charge the other battery back while I driver). My H2 has stranded me too many times in the last 2 years (at least 8 times). Anyone ever wire up such a setup?

Thanks
